PORTABLE vIsE.

Application filed Aug-ust 24, 1922. Serial No. 584,158.

of Massachusetts, and l/VILFRED E. TArr, av

citizen of the United States, and a resident of Wollaston, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Portable Vises, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Qur present invention relates to vises, and more particularly to improved portable and adjustable vises.

The average ordinary vise, which is a bench vise, while admirably adapted for use on a fixed bench or in a shop, is not portable 2G in the sense that such term is generally understood, and particularly such bench vises are not adapted for use on relatively small boats,automobiles, or in small garages in which situations there is never -too much room and ordinarily no room whatever in which to place. a bench such as would be required for a bench vise. In consideration y of the present invention, we may discard the ordinary small vise, termed portable, provided with a set screw or thumb nut, by means oi' which the same may be clamped to a board, or the like, as such vises are ordinarily too `small to be of any practical use and it is practically impossible to place them rigidly enough on a bench to hold work of any size. y

In our present invention we have devised a vise that will have all of' the good features that are present in bench Yises and all of the good featuresy ot ,so-called portable vises in that our present invention relates to a really portable vise and .at the same time has none of the disadvantages now inherent in such portable vises, Our improved portable vise is adapted for use in situations such as a motor boat, where-repairs have constantly to be made to machinery, in a small garage where there `is ordinarily not room for a, bench and is small enough to be carried under the seat, or in the tool box,

of an automobile, and may be positioned f against a post, tree, or any upright support that may be at hand. `As constructed, our improved vise is capable of swingingfmovement in a horizontal plane, or swinging movement in a vertical plane, or a combined horizontal and vertical swinging movement, as may be desired.

The principal object of our invention, therefore, is an improved portable vise.

Another object otour invention is an improved portable vise adapted for easy connection to an upright of Vany character and capable of swinging movement in a horizontal plane and having means for clamping the vise in 4any posit-ion in such plane.

Another object of our invention is an improved portable viseof the type above described, capable of swinging movementl in such planes as may be desired.

Other objects and novel features of the construction and arrangement of parts comprising our inventionxvill appear as the de-y scription of the invention progresses.

In the drawings illustrating the preferred embodiment otour invention,

Referring to the drawings, l0 designates a wall, post, plank, or other uprightsupport to which may be fastened, by bolts 11, a frame member comprisinga plate 12ste which is riveted near its top and bottom ends` lugs 13, the top lug 13 being .provided on its top surface with teeth 14 and the` bottom lug 13 provided on itsk bottom surface with teeth l5. These lugs 13 `also have screwed and riveted therein and extending` upwardly from the top lug and downwardly on the line from the bottom lug threaded bolts 1G. Arranged parallel to the plate 12 and of substantially the same length 'thereof is a tlat plate 17 having secured near its top end by nut 18 a lug 19 provided with teeth 2O adapted to mesh with the teeth 14 Of 'the top lug 13 and having secured near its bottom end by nut 21 a lug 22 provided with teeth 23 adapted to mesh with teeth 15 on the bottom lug 13. The lugs 19 and 22 are drilled to allow the bolts 16 to slide. freely therethrough and the bolts 16 are of a length to extend beyond such lugs 19 and 22. l/Vith the parts assembled, as so far described, there is spring enough in the ilat plate 17 to allow the lugs 19 and 22 to be rotated relatively to the lugs 13, the cooperating teeth 14 and 20 and 15 and 23 sliding` past each other in this operation. Screwing on to the top bolt 16 is an internally threaded member 24 through the end of which is slidably mounted a rod 25 provided at each end with an enlargement 26, while screwing onto the bottom bolt 16 is an internally threaded member 27, through the end of which is slidably mounted a rod 23 provided on each end with an enlargement 29, the lrods 25 and 23 being utilized to screw the members 13 and 19 and 13 and 22 respectively into close association to prevent rela-tive movement thereof and hold the plate 17 in adjusted position.

Near the top end of plate 17 and below the lug 19 is riveted the inner end of a cylindrical bar 30, the outer end of which is threaded at 31 to receive the internally threaded inner end of a tube 32, and on the extreme outer end of this tube 32 is secured, by rivets 33, a. xed vise jaw 34. The lower end of the xed vise jaw 34 has a depending` lug 35 that is slotted to receive ythejupperl end of a strut or bar 36, a pin 37 being utilized to hold the strut or bar 36 in position or, if desired, such pin 37 may be removable to allow the tube 32 to be swung downward substantially forwardly to the bar 17. The lower end of this strut or bar 36 is pivotally mounted by means of pin 33 to a bifurcated lug 39 riveted to the lower end of the plate 17 adjacent the lug 22.

The lower portion o-r edge of the tube 32 is slotted at 40 from a point inside of the lixed vise head 34 to a point adjacent the screw connection 31, and in this slot and within the tube 32 slides a bar 41 provided at its upper end with? an internally threaded enlargement 42 through which is adapted to work the threaded end of a lead screw 43. The outer end of this lead screw 43 is enlarged and extends beyond the outer limits of the fixed vise head 34, and through this outer end is slidably mounted a rod 44 provided at each end with an enlargement` 45,

and by means of which bar 44 the lead screw is rotated. rllhis enlarged end of the lead screw is provided at a. point within the fixed Lasciato head 34 with a circumferential groove 46 in which fits the reduced end 47 of a headless screw 48 that screws through the fixed vise head 34, as shown clearly in Fig. 3. Slidably mounted on the tube 32 is a movable vise head 49 provided with a. depending lug 50 to which is secured by rivets 51 the lower end of the member 41.

The operation of our improved invention is as follows: The vise may be kept in an assembled position, as shown in Fig. 1, or should the pivot connection be substituted for the screw connection 31, then the devise may be kept in folded or closed position by removing the pin 37, moving the upper end of the bar or strut 36 from engagement with the lug` the tube 32 and associated parts being then folded substantially upwardly to the bar 17. ln either event, the device may be kept in a relatively small space, such as under the seat of an automobile, in the tool box or other receptacle, and when it is desired to place the vise in position, the bolts 11 are utilized to screw the plate 12 and all parts associated therewith into position against a post, a stu dding, a stanchion, or the like, the members 24 and 37 backed off to allow a swinging movement of the plate 17 and associated parts into the position desired and the lugs 19 and 13 and 22 and 13 clamped to hold the parts in adjusted position. `When used in a garage or boat, it is preferably desirable to allow the plate 17 and all parts carried thereby to be attached permanently in position, and after use, the vice portion carried by the tube 32 may be swung on its pivotal connection upwardly to the wall or side of the boat, or the tube- 32 carrying the vise portions 34 and 49 may be swung downward substantially forwardly with the plate 17.

`While we have necessarily described the preferred embodiment of our invention some what in detail, it is to be understood that we may vary the size, shape, and arrangement of parts constituting our improved construction without departing from the spirit of the invention,

Having thus described our invention, wh at we claim as new is:

1. ln an improved portable vise, the combination of a plate, means for securing said plate in position, a frame, connections thereon, pivotal connections at each end of said plate cooperating with the connections on the frame, a. projecting arm attached to one end of said frame, a. vise having a portion thereof formed integral with said arm, and means for supporting the outer end of said vise extending between the vise and the lower end of the frame.

2. In an improved portable vise, the combination of a plate, lugs secured at each end of said plate and provided on opposite faces with a plurality of radially formed teeth, pivot members extending outwardly said lugs,
